Dark Reactions of Photosynthesis: The Calvin-Benson Cycle Related Study Materials
The Light Independent Reaction, Calvin Cycle, Calvin Benson Cycle, ..
Since he discovered that there was a "cycle" he named it the "Calvin Cycle."
Over the 10 years of experiments he discovered every step that a plant undergoes to create its own sugar substance to be able to make their own sugars.
Calvin proved that photosynthesis did not occur in carbon dioxide, but in the chlorophyll where carbon dioxide is a very important component.
The purpose of Melvin Calvin's experiment was to trace the route that carbon took during photosynthesis.
Following the tracer carbon would either prove the previous theory that carbon dioxide was the site of photosynthesis, or prove that the carbon dioxide was broken down and converted into carbohydrates and other necessary molecules.
The Calvin Cycle converts the Carbon Dioxide taken in from the environment (with the help of NADPH and ATP from the Light Reaction) into Glyceraldehyde 3-Phosphate which is then converted into carbohydrates and other molecules.
What happens during the Calvin cycle in photosynthesis
(Chromatography is used to separate mixtures of substances into their components, which was used to locate the carbon at the different stages.)
The materials used in the discovery of the
Calvin Cycle are:
- Chlorella Pyrenoidosa
- Audio radiogram
- Radioactive Isotope Carbon-14
- Methanol (Alcohol)
- Chromatography Paper
- Heating Source

Based on his experiments of series of radioactive isotopes, chromatography paper, and autoradiography, Calvin spent nearly 10 years to identify the compounds that carbon was converted to during the light independent cycle of photosynthesis.
In the photosynthesis and initial carbon fixation occur at night and a 4-carbon acid is stored in the cell's vacuole. During the day, the Calvin cycle operates in the same chloroplasts.
3PG in Calvin-Benson cycle during photosynthesis?
Plants are able to synthesize carbohydrates through the process of photosynthesis. During photosynthesis, plants capture the energy of the sun and convert the sun energy to chemical energy during the light reactions. All of photosynthesis occurs in the chloroplast. During the light dependent reactions, oxygen is evolved and ATP (adenosine triphosphate—a compound that can supply energy to chemical reactions in a cell) is produced. ATP is the chemical energy produced during photosynthesis. Plants then use that energy to take carbon dioxide (a gas) and fix it ultimately into glucose (a solid sugar).
In the photosynthesis takes place in a chloroplast of a thin-walled mesophyll cell and a 4-carbon acid is handed off to a thick-walled bundle sheath cell where the Calvin cycle occurs in a chloroplast of that second cell. This protects the Calvin cycle from the effects of .

Carbon dioxide is captured in a cycle of reactions known as the Calvin cycle or the Calvin-Benson cycle after its discoverers. It is also known as just the C3 cycle. Those plants that utilize just the Calvin cycle for carbon fixation are known as . Carbon dioxide diffuses into the stroma of chloroplasts and combines with a five-carbon sugar, ribulose1,5-biphosphate (). The enzyme that catalyzes this reaction is referred to as , a large molecule that may be the most abundant organic molecule on the Earth. This catalyzed reaction produces a 6-carbon intermediate which decays almost immediately to form two molecules of the 3-carbon compound 3-phosphoglyceric acid (). The fact that this 3-carbon molecule is the first stable product of photosynthesis leads to the practice of calling this cycle the C3 cycle.

This second half of photosynthesis goes by many names: The Calvin Cycle or the Calvin-Benson Cycle (named for the scientists who elucidated the pathway), the light independent reactions, the "dark reactions" (but remember, this can and normally does occur in the light) and even simply as carbon fixation (as the gas CO is "fixed" to a solid form).The carbohydrates produced through photosynthesis can be used for energy storage as the polymer (a long chain) starch and for structure as the polymer cellulose that makes up part of the cell wall of a plant cell.
